Bit of a mixed bag.....one lady on customer service would answer emails straight away, but the booking team were a nightmare with regards to dates to have fitted and never replied unless went through CS too. Found booking process a pain to as having to answer loads questions about the electrical supply at home and where this and that was......thought they were the specialists, don't ask me! Also had to have other work done prior so in the end costed nearly twice as much as at start. Plus side as well as the CS agent Olga and the installer Sean were brilliant.
